PAPER-CALENDER.

SPECIFICATION forming part of Letters Patent N 0. 268,499, dated December 5, 1882, Application filed August 22, 1882. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM D. KI'rEs, a citizen of the United States, residing at Russell, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Doctors for Paper-Galenders, of which the following is a specification, reference being had to the annexed drawings, forming a part of this specification,in which- Figure l is a perspective view of the machine, and Fig. 2 is a detached plan view of the doctor.

This invention relates to the device which is applied to operate at the junction of two calender-rolls to guide sheets of paper as they come around one roll onto and around the next one, and which device is technically known as the doctor.

The object of my invention is to so improve the construction of said doctor, apart of which bears constantly against the face of the calender-rolls while they revolve, as to prevent the wearing of any grooves or depressions in the surface of said rolls, whereby they become seriously injured; This I accomplish by constructing said doctor with a I contact-edge Heretofore said doctors have beenmade with a series I of thin metallic fingers whose ends lie against said rolls, and after the latter have run for a certain time with said fingers pressing thereon grooves become worn in the rolls, and paper passing between rolls so worn has left upon it the impress of said grooves, greatly to its injury; but when thebearing-edge of the angular-shaped plain metal plate, having a continuous edge, set between the taperoll and I the meet of the calender'rolls. o are weights hung on arms projecting from said doctor, which weights cause the contact-edge of the doctor to bear up against the face of the upper roll and cause sheets of'paper coming between the rolls to be guided downward under the tapes 0 next below.

The doctor is hung in the calender-Frame in the usual way, except that it is located in the rear of the tape-roll. The improved unbroken edge of the doctor is indicated In' Fig.2,a plan view of the doctor detached by the letter 0 and d indicates the supporting-bar on which are its bearings.

Now, having described my inventionflwhat I claim is- The within-described improved doctor for paper-calender rolls, consisting of the plate 0 having plain faces free from all obstructions, and a continuous edge secured tothe pivoted bar d, and adapted to have its edge borne by suitable weight upon the surface of a calenderroll, for the purpose set forth.
